# The coefficient in 665 x 10^{4} is

We will use Scientific Notation to answer this question.

## The coefficient in 6.65 * 10^{4} is 6.65

The given number 6.65 * 10^{4} is represented in Scientific Notation.

## Explanation:

Scientific notation allows us to express very large or very small numbers in a convenient way. This notation uses a coefficient (a number between 1 and 10) and a power of ten sufficient for the actual number.

Here, the coefficient is 6.65 and the exponent is 10^{4}.
